Configuring Remote Access for AN and Passport ARN Routers

Verifying Your Configuration

You can use the getcfg command to verify the following:

•Whether the router is set to boot using a local or remote boot image

•Whether the router is set to configure using a local or remote configuration file

•The configuration of the serial, Ethernet, and token ring (ARN only) interfaces

To display the configured startup options for an AN/ANH or ARN router, enter the following command at the Technician Interface or AN Monitor prompt:

getcfg

The following sample output shows the default configuration for an AN/ANH with one Ethernet interface and two serial interfaces:

Boot Options

boot image=local boot config=network

Netboot Parameters:

XCVR1..None

COM1...EZ-Install

COM2...EZ-Install

The following sample output shows the configuration for an ARN with one Ethernet interface, one token ring interface, and five serial interfaces:

Boot Options

boot image=local boot config=network

Netboot Parameters:

MAU1...None

XCVR2..None

COM1...EZ-Install

COM2...EZ-Install

COM3...EZ-Install

COM4...EZ-Install
